Play Bison Moon: Thunder Charge

Bison Moon: Thunder Charge by Northern Lights Gaming takes its wildlife theme into a feature-led 5-reel slot where Red Moons can activate several collection mechanics, including the expanding Thunder Charge respin bonus. 

In our slot games range at BetVictor, the game combines 25 fixed paylines with Stellar Moon, Moon Collector, Bison Stampede and Lightning Eagle features. 

Bison Moon: Thunder Charge uses a North American wilderness theme built around bison and moon imagery. Bears, wolves, eagles and raccoons form the premium symbol set, while A, K, Q and J make up the lower-value symbols. 

Red and Blue Moons have distinct feature roles, while the Bison character appears as the Wild. 

• The Bison Wild substitutes within regular paying combinations. 
• Exactly five Red Moons activate the Stellar Moon Bonus, while six trigger Thunder Charge. 
• Red Moons that do not trigger either feature can contribute to the Moon Collector. 

Stellar Moon Bonus 

Exactly five Red Moons trigger Stellar Moon. Their displayed cash values are combined, then multiplied by a randomly selected 1x, 2x, 3x, 4x, 5x, 10x, 20x, 50x or 100x multiplier. 

Moon Collector 

Red Moons can feed the Moon Collector during the base game. On a random activation, it adds enough missing Red Moons to create the six-symbol Thunder Charge trigger. 

Bison Stampede 

Bison Stampede can activate randomly after a base-game spin. It either fills selected reels with Bison Wilds or places six or more Red Moons onto the grid, triggering Thunder Charge. 

Lightning Eagle Jackpot 

Lightning Eagle symbols fill five collection boxes. Completing all five opens a prize wheel that can award 5x, 20x, 50x, 75x or 250x, a jackpot result or entry to Thunder Charge. 

Thunder Charge Bonus 

Six Red Moons start Thunder Charge with three respins. The feature begins with four active rows on a potential 5x6 grid, while the top and bottom rows are locked. 

Blue Moons remain in place and receive the current shared cash value. When one or more new Blue Moons land, the respin count resets to three and the shared value doubles for later Moons. Two Keys are required to unlock each additional row.

The base game uses five reels, three rows and 25 fixed paylines. Regular wins require at least three matching symbols on adjacent reels, beginning from the leftmost reel. 

The conventional line structure keeps the main spin straightforward, while Red Moon and Lightning Eagle collections add progression between feature activations. The Bison Wild can assist regular combinations. 

• Bison Moon Power Combo: Another entry in the same series, using bison, moon imagery and wilderness visuals. Its progression instead combines expanding areas, multipliers and collection modifiers. 
• Bison Moon Ultra Link&Win: This earlier Bison Moon title also centres on locking Moon symbols and grid expansion, giving it one of the closest mechanical connections to Thunder Charge. 
• Bison Ridge Power Combo: Bison imagery and interacting modifiers provide the thematic overlap, although its Power Combo mechanics differ from Thunder Charge's Moon collection and respin structure. 

We think Bison Moon: Thunder Charge stands out by placing several routes into its main respin feature around the same Red Moon mechanic. The 5x3 base game and 25 paylines remain easy to follow, while Moon Collector, Bison Stampede and Lightning Eagle add more layers between standard spins. 

Within our casino games selection, this Northern Lights Gaming release is likely to suit players who prefer familiar fixed-line mechanics but want a more progressive feature structure. Thunder Charge adds the greatest complexity, particularly as Blue Moon values increase and Keys open additional rows.
